I just built a new system (see specs below) and installed windows 7 in IDE mode. After noticing some performance (and WEI HDD score) issues, I read about AHCI. I found the fix to switch the registry to enable AHCI, then rebooted and switched my bios to AHCI mode. Scores went up in WEI, and benchmark results as well. The issue is, every once in a while (anywhere from 5-20 minutes) I get a freeze that lasts 2-3 seconds, then everything is fine. Is this an issue from switching modes after windows was already installed? Help!
